This is new upgrade version:

1, increased anti-interference function,

2, reduce the large current heat by 30%,

3, starting power increased from 135W to 170W (3S40A)

3S 40A 12.6V 40A lithium battery protection board (comes with recovery function-AUTO Recovery)

Scope: Nominal voltage of 3.6V, 3.7V lithium battery (including 18650,26650, polymer lithium battery)

Product Size: 42 * 60 * 3.4mm (balanced version)

Product weight: 9.8g (balanced version)

Charging voltage: 12.6V – 13.6V

Continuous discharge current (upper limit): 40A (if the cooling environment is not good, please reduce the load current use)

Continuous charge current (upper limit): 20A

Balance version: suitable for starting current below 80A, power 135W below the drill.
Note 1: The successful start of the electric drill requires 3 15C-20C power batteries, or 6 10C-15C power batteries (ordinary 18650 can not start drill! ! !). Note 2: Connect 0V, 4.2V, 8.4V, 12.6V,in strict accordance with the diagram. Do not intentionally short circuit. Note 3: When the battery is charged, “430” resistance heating is a normal phenomenon, indicating that the equalizing circuit is working; if the “430” resistance is also heating in the state of not charging, please check whether the wrong line is connected.
Note 4: 3 groups of batteries in series, please ensure that the voltage of each group of batteries, if not the same, please fill each battery separately and then use in series. The The Discharge test, the voltage drop faster battery that group is poor battery.

For some of the poor basis of electronic customers to explain: balanced charge is only auxiliary functions, try not to put a good battery and poor battery mixed together! 3 sets of battery capacity / resistance closer to the better! (2 good battery +1 Poor battery use effect = 3 poor battery use effect). Package include: ​1* 3S 40A Protection Board
